Scientific Name: Astyanax cordovae (Günther, 1880)
Tetragonopterus cordovae Günther, 1880

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2ce; B1ab(i,iii,v) ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Needs updating
Assessor(s): Reis, R & Lima, F.
Reviewer(s): Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)
Assessed as Vulnerable due to an inferred population decline of greater than 30% over the past ten years. This is due to water pollution and introduced species but also because of a continuing decline in habitat quality in the Cordoba region.

Habitat and Ecology [top]

Habitat and Ecology:A. cordovae is a benthopelagic (ecological region at the lowest level of water body) species.

Threats [top]

Major Threat(s): A study on the conservation status of the ichthyofauna of Sierras Pampeanas, Cordoba, concluded that A. cordovae had one of the highest conservation priorities (Orlandini et al. 2001). This is largely due to it being endemic to Cordoba; an area which is threatened by alterations in vegetation cover, water pollution and the indiscriminate use of biological resources. The Rio Primero goes through Cordoba City where pollutants enter through mostly untreated effluents. Along the Río Segundo, different industries exist that also pump effluents into the river without treatment (Western Hemisphere Shorebird Reserve Network 2003). Fish species in the region have also been impacted by the introduction of economically important fish species, which compete with the native species for resources such as food and breeding sites (Orlandini et al. 2001).

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place. The extent of damage the water pollution is causing to the species and habitat needs to be addressed.
